What to do
AI-suggested
A fix has been applied in the Linux kernel source code, adding a scope-based guard to ensure the runtime PM reference is held during xe_gt_reset() calls. Users should update to the fixed Linux kernel version containing commit 7937ea733f79b3f25e802a0c8360bf7423856f36 or later. No other mitigation is indicated.
Description
A vulnerability in the Linux kernel's drm/xe component was fixed to address a missing runtime power management (PM) reference in the ccs_mode_store function. The flaw involved calling xe_gt_reset(), which internally calls xe_pm_runtime_get_noresume() without holding the required outer runtime PM reference, causing warnings and potential improper power management behavior. The fix adds a scope-based guard to ensure the runtime PM reference is held properly during the call.
